WASHINGTON — A federal official says a second safety agency will investigate the fatal crash of a Tesla sedan while the vehicle's Autopilot self-driving mode was in use. Rob Molloy heads the National Transportation Safety Board's highway investigations division. Molloy says a team of investigators will go to Florida next week to examine the wreckage of the Tesla Model S. The National Highway Traffic Safety Administration announced last week that it is investigating the May 7 crash near Gainesville to see if the Autopilot system is defective. The agency has said a truck made a left turn front of the car, but neither the Autopilot nor the driver applied the brakes. The driver was killed. Molloy says NTSB's investigation will take a comprehensive look at the entire incident.
